Rob has written a good post to read, about M42-lenses, on Brian Auers Epic Edit-blog. He uses the same DSLR as me, the Canon EOS 350D (mine is on it’s last breath). Like Rob I have used the Pentacon 29mm/2.8 and think it’s an underrated lens. I sold it some time ago though.
My current M42 lenses, which I like:
- Asahi Super-Takumar 85mm/1.9
- Asahi Super-Multi-Coated Takumar 55mm/1.8
- Asahi Super-Takumar 135mm/3.5
- MC Helios 44-3 58mm/2
- Auto Yashinon-DX 50mm/1.7
- Tele-Tokina 105mm/2.8
- Pentacon Auto 50mm/1.8
